Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a pressure-applying bone fixation device for the arm. Background Technology

[0002] Postoperative immobilization is a crucial step in the treatment of arm surgery or other upper limb injuries. Traditional immobilization methods, such as using rigid materials like plaster casts or metal braces, while providing necessary support, often lack flexibility and comfort. These materials are not easily adjustable and cannot be tailored to the patient's specific recovery progress, potentially leading to discomfort or restricted blood circulation. Postoperative limbs are prone to swelling, requiring pressure bandages to reduce it. Traditional pressure bandages typically use cotton pads, but these are prone to slippage, inconvenient to apply, and difficult to reposition. Furthermore, inconsistent application techniques can result in uneven pressure, potentially causing pressure sores at bony landmarks such as the ulna. These issues highlight the limitations of current postoperative immobilization techniques in terms of adaptability.

[0003] In recent years, with the development of materials science and smart technology, some innovative postoperative fixation devices have emerged. These devices attempt to use softer materials that better adapt to the patient's body shape and integrate sensors and intelligent control systems to achieve more precise pressure control and monitoring. For example, an orthopedic arm fixation device includes a lighting component and an arm support fixation component. The arm support fixation component is positioned above the lighting component. The adjustable, multi-segment lighting component perfectly matches the surgeon's illumination during operation. Furthermore, the arm support fixation component adapts to the patient's arm position when placed on the device, quickly adjusting to the most suitable arm position based on the patient's arm shape, greatly improving patient comfort during fixation.

[0004] In addition, there is a temporary arm fixation device for surgery and a postoperative shaping device, including a reservoir, a thermoplastic splint cover, and an adjustable cover. During surgery, the height of the adjustable cover can be adjusted via a height-adjusting component to effectively fix the affected limb, allowing for proper positioning of the arm during the procedure, facilitating the surgeon's work, reducing the number of surgical personnel, and shortening surgical time. After surgery, the thermoplastic splint cover can be heated using a heating device to personalize its shape according to the patient's individual needs.

[0005] Therefore, there is an urgent need to develop a fixation device that can provide stable support and adapt to changes in arm swelling, while also possessing good adjustability and comfort. This is a pressing issue in the field of postoperative fixation technology. Furthermore, this device should be able to flexibly adjust according to the patient's recovery progress to adapt to the physiological changes in the patient's arm, thereby reducing patient discomfort and improving the convenience of treatment.
